How to Subtract Fractions with Like Denominators - Adding and subtracting fractions are basically the same. There isn't much difference between the two. However, we cannot even say that they are absolutely the same. Let's learn how we can subtract fractions. But before we take a dive into learning it, let's understand what are like denominators. When you see fractions with like denominators, this means that the whole fraction or number is divided into same number of pieces or numbers. Like denominators are also called common denominators. They can be subtracted following the below-mentioned steps: 1. Analyze the whole number carefully. If it's a mixed number, make sure to convert it into a fraction. 2. Now subtract the top numbers (the numerators) and write the answer with the same denominator. 3. When you have the answer, make sure to simplify it if there’s a need. Consider the following example: 3/4 - 1/4 The denominators are the same, and you simply have to add the numerators (top numbers). The answer is 2/4. Now simplify the fraction, and you get your final answer. Students will learn how to subtract fractions that have like denominators.
